IMPROVEMENT IN OSCILLATING CABINS FOR VESSELS.

Specification forming part of Letters Patent No. 140,978, dated July 15, 1873; application filed May 15, 1873.

To all whom t may concern:

Be it known that I, BERNHARD WEISKER,

Y of the city, county, 'and State of New York,

' use the same, reference being had to the ac companying drawing forming part of this specitication, in which drawing- Figure l represents a longitudinal vertical section of my invention. Fig. 2 is a transverse section ot' the same in the plane a: Fig. 1.

Similar letters indicate correspon ding parts.

This invention consists in the arrangement of a door in the interior .of a vessel, said door being made to oscillate on pivots secured in a swinging frame, while both the door and the frame are subjected to the action of balance-pendulums in such a manner that by said balancependulums the tloor is retained in position against the weight or pressure which may be brought to bear upon it, while said floor is free to accommodate itself to the rolling and also to the pitching motions of the vessel.

In the drawing, the letters A A designate the walls or partitions which separate the cabin from the remaining portion of the vessel. In two of these partitions-one opposit'e the otherare secured pivots a a, which support a frame, B, so that this frame is free to oscillate in a plane at right angles to the keel of the vessel. rI`he pivots a a are situated in the lower parts of the partitions A A, and in the upper parts of said partitions turn rock-shafts b b, which are parallel to the pivots a a and right above them. On the inner ends of these rock-shafts are mounted levers c c, which connect by rods d d with the corners of the frame B, and on the outer ends of said rock-shafts are mounted pendulums C, which carry heavy weights D, and the lower ends of which are guided in suitable grooves or channels.

By means of these balance-pendulums the frame B is free to follow the rolling motions of the vessel, and at the same time the weights D are so proportioned that any ordinary weight or pressure brought to bear upon said frame will not perceptibly change its position. Y

In the sides of the frame B are secured pivots e e, which support the ioor E, the di'- rection of the pivots c e being at right angles to that of the pivots a a., so that while the frame B oscillates in a plane at right angles to the keel the ioor E oscillates in a plane parallel to the keel; or, if desired, the frame may be made to oscillare in a plane parallel to the keel, and the iloor in a plane at right angles thereto.

In the upper part of two of the partitions A A is mounted a rock-shaft, F, which eX- tends at'right angles to the rock-shafts b b, in a direction parallel to the pivots c e, and right above the same across the upper portion of the cabin. On the middle of this rockshaft is mounted a lever, Gr, (see Fig. 1,) the ends of which connect by rods f f with the iioor E,and,on the extreme ends of said rockshaft are secured two pendulums, H, which carry heavy weights I, and the lower ends oi' which are guided in suitable grooves or channels.

By this arrangement the floor is free to follow the pitching motions of the vessel, while the balance-pendulums prevent the door from tipping over by the weight or pressure which may be brought to bear upon it.

It will be readily understood from the above description that by my-invention a cabin is produced the floor of which will retain its horizontal position independent of the motions of the vessel, while the weights of the balance-pendulums C and H are so proportioned that the position of the oor will not be perceptibly disturbed by any ordinary weight or pressure that may be brought to bear upon it.

What I claim as new, and desire to secure
